Of course, Alvarez homered in his debut off of Dylan Bundy on June 9th, and ended up hitting 27 home runs over 87 games, leading Houston back to their second World Series in the past three years. That home run total ties the record for the most home runs by a rookie who played less than 100 games in the regular season. He ended up playing in 143 games between the minors and majors this season, finishing with an average of .324 with 50 home runs and 149 RBIs, as his 1.067 OPS ended up being the highest ever for a rookie with at least 350 plate appearances.
Meanwhile, the National League Award was also an easy decision due to Pete Alonso breaking a New York Mets franchise and major league rookie records, as he was named the award winner on Monday. His 53 home runs a set records for most by a rookie, as he also knocked in 120 runs. He nearly won the award unanimously, getting 29 of the 30 possible votes, beating out Mike Soroka of the Atlanta Braves and Fernando Tatis Jr. of the San Diego Padres. Soroka did have a 2.68 ERA and 13 wins, while Tatis finished with a .317 average, despite ending his season in the beginning of September due to injury.
Alonso's home run total broke the major league rookie record previously set by Aaron Judge of the New York Yankees, who hit 52 in 2017. He is now the sixth Mets player to ever win the award, and the first since Jacob deGrom won it in 2014. Overall, he is just the 30th player to have 50 home runs in a season, and joins Judge, Giancarlo Stanton, and Chris Davis as the only active players to have done so. His 120 RBIs are the seventh most ever by a rookie, and the most since Albert Pujols drove in 130 runs for the St. Louis Cardinals in 2001. To add to his tremendous season, which almost rallied the Mets to a National League Wild Card spot, Alonso also won the Home Run Derby at the All-Star Game in Cleveland this past July. He will hope to keep that momentum alive heading in to the 2020 season under new manager and former Met slugger himself, Carlos Beltran.
